It is not clear what the interaction should be when the user clicks on a row. Do you want:

The Javascript to download the file and show a preview or contents

Allow the user to edit the file

Get metadata about the file

The user to be directed to another action method which downloads the file

I'm going to lay out the stubbing for a file download, but you can change it to whatever interaction you want by changing the action method logic. What you should do is pass the file name through GET in a URL (Since this is the MVC way). The view would be (the formatting is missing the @'s because the code formatter is not having it for me at the moment):

You pass the ftp doc name via GET to the action method by adding the new { id = item } to the html helper. You would use the string called 'id' in this case in your logic to retrieve the document, or if your original intent was NOT to download the doc, you could implement whatever you wanted in a similar way.

By the way, make sure to use the correct overload of @Html.ActionLink - if you notice I put 4 parameters, null being the last. In MVC5 they changed this and if you don't put the 4th parameter you will get /controller/action?id=Value rather than /controller/action/value in the URL.
